“After years of seeing people overcomplicate nutrition, I decided it was time to step in and take control of the situation. Listen, building muscle is about providing a surplus of calories to compensate for the muscle breakdown that happens during training – this much is obvious. What there hasn’t been – until now – is a formula that provides a convenient source of quality nutrients to force muscle tissue to adapt to the stimulus. My product changes this: it’s a robust blend of protein, vitamins, minerals, creatine, combined with complex carbohydrates and minimal fat content. We’ve fortified it to enhance muscular recovery and encourage tissue growth. There are zero fillers in Game Changer Mass meaning all the calories contribute towards building lean muscle tissue, NOT just general ‘mass’.”



Whey Protein Concentrate is a byproduct of cheese, making it highly bioavailable substance that the body can rapidly absorb, especially after physical exercise, in order to repair the muscle tissue and build new tissue. Time and time again, studies have shown that supplementing with whey protein led to improvements in lean muscle mass building and recovery. The importance of whey protein for physically active people can’t be understated.

Creatine Monohydrate has been used and studied for decades. It is effective for both short-term and long-term muscle growth. Creatine enables your muscles to produce energy during heavy lifting or high-intensity exercise. Creatine plays an important in cell signaling, which means a better mind-muscle connection. It also aids in muscle tissue repair and growth. Studies have shown that it reduces protein breakdown, meaning that more protein is being used to repair your muscle tissue after physical exercise. Creatine will make you increase your rep count in each training session, which is a key factor in long-term muscle growth. Creatine also increases cell hydration for bigger muscle pumps, which in turn supports your muscles to become fuller.

L-Glutamine is one of the most abundant type of essential amino acid present in the bloodstream. One of the primary roles that L-Glutamine has is to decrease high levels of ammonia. This means that the body can recover faster after physical exercise, thus reducing post-workout fatigue. Studies have shown that this amino acid aids in muscle growth and prevents muscle wasting (catabolism), especially after an intense training session. By preventing the body to use its muscle tissue for energy, L-Glutamine boosts the metabolism so that it uses the stored fat reserve for energy.

BCAA 2:1:1 Complex – Most of the amino acids are created naturally by the human body, but putting a stress on the muscle tissue, such as running, cycling, swimming, physical exercise, and weight training depletes the Amino Acids reserve and makes the body enter the catabolism phase, where it consumes the muscle tissue in order to replenish its resources. BCAA combat this and ensure a constant trickle of nutrients in the blood flow.

L-Leucine is an essential amino acid, usually found in certain foods such as: eggs, fish, and chicken. L-Leucine can increase growth hormone production, while also helping to increase the physical endurance levels.

L-Isoleucine is an essential amino acid that acts as a catalyst for protein synthesis. It can boost the anabolic processes throughout the body, aiding the in the development of specific hormones like growth or testosterone.

L-Valine is an essential amino acid acts as a fuel reserve for the human cells. A lack of L-Valine in a diet leads to a growth deficit of the muscle tissue.

L-Arginine is an important type of amino acids as it plays a crucial role in building protein. The human body has the ability to produce L-Arginine naturally, but the additional L-Arginine will boost the creation and absorption of protein. As a result, a higher intake of L-Arginine will aid you in developing lean muscle mass. Apart from protein benefits, L-Arginine has been shown through medical studies to reduce blood pressure throughout the body, while improving the overall blood circulation.

Calcium Alpha-Ketoglutarate is a mineral type of calcium that aids in the developing of muscle mass. It can prevent catabolism by protecting the muscle from being used as an energy source, while also improving the blood flow throughout the circulatory system. Studies have shown that Calcium Alpha-Ketoglutarate can improve the healing and recovery time after high intensity exercise.

L-Lysine is an essential amino acid that plays an important role in protein synthesis for developing muscle tissue after physical exercise. While aiding the protein absorption, L-Lysine helps the transportation of fats across cells to be burned for energy. Apart from other essential amino acids, L-Lysine helps in the formation of collagen, a type of protein that aids in the developing and repairing of joints and connective tissue.

Citrulline Malate (2:1) is a non-essential amino acid. It’s usually scarce in people’s daily diet, although it plays a very important role in many biological processes. Citrulline Malate decisively contributes to optimizing the blood flow, which affects the performance of most bodily functions. When ingested, your body converts it into L-arginine and then into nitric oxide. Nitric oxide is one of the compounds that makes the blood vessels wider when you exercise, thus bettering your blood flow. Improved blood flow means that more oxygen and needed nutrients are getting to the muscles.

L-Citrulline is a naturally occurring type of amino acid that is commonly found in food, while also being produced by the human body daily. L-citrulline is converted by the body into other types of amino acids. It has been documented that L-citrulline can increase the speed of transporting other types of amino acids throughout the body, further enhancing the absorption rate. As a result of this speed increase, the blood flow will be streamlined, while reducing the overall blood pressure.

L-Methionine acts as an antioxidant, protecting the body from tissue damage, removing the excess levels of ammonia. As a result, L-Methionine can boost the developing and protection of muscle tissue.

Vitamin B1, also known as Thiamin, promotes the energy production from carbohydrates and fats, aiding the body in developing lean muscle mass and not creating fat reserve. Vitamin B-1 calibrates the normal function of organs, such as the brain and heart. Vitamin B1 supports the nervous system by transporting the extra energy to certain parts of the body that frequently require more energy, such as muscles and brain.

Vitamin B2 aids in the absorption of protein, further preventing it from being eliminated from the body. Alongside other types of Vitamin B, Vitamin B2 helps in energy supply creation and conservation. This energy is being created from fats and other oils. As a result, the muscle mass is not affected by catabolism, while also improving the protein synthesis.

Vitamin B3 or Niacin is a vitamin that helps the transformation and assimilation of food, nutrients, and other amino acids into energy for your body. This boost of energy can help you push past your limits and enable you to give everything you’ve got while training. Vitamin B3 also helps lower cholesterol, boost brain and skin function and improve joint mobility.

Vitamin B5 or Pantothenic Acid is a highly important vitamin for the daily human life. It can create new blood cells, while also transforming the food into energy. By transforming the food into energy, Vitamin B5 prevents the body from storing the extra nutrients as fat, improving the metabolism. By creating new blood cells, it aids the oxygen flow through the body, boosting your overall physical endurance.

Vitamin B6 is mandatory for the human body in order to function properly, as it aids in the processing of sugar, fats, and proteins, which is highly important for people who want to add lean muscle mass. Vitamin B6 is also used by the body in order to further help the development of brain, nerves, and skin.

Vitamin C is a powerful antioxidant that boosts the immune system. It’s also helping white blood cells function more effectively, strengthening your skin’s defense system. Vitamin C supports the natural production of L-Carnitine in your body, further enhancing your fat loss efforts. It also can lower heart disease risk factors, including “bad” LDL cholesterol and blood triglycerides.

Vitamin D3 is fat-soluble vitamin, making it a highly effective fat and oil burner from the body. Vitamin D3 promotes the absorption of calcium and phosphorus from foods, further fortifying the bones, while also giving a boost to strength. Because Vitamin D3 makes the calcium to be assimilated much faster, it prevents the risks of bones fractures and osteoporosis.

Vitamin E is an important vitamin that the body uses for proper functions of many organs. Vitamin E has antioxidants properties, which protects the muscle after physical exercise, while improving the overall muscle strength. Another benefit that Vitamin E provides an increase in energy and an enhancement to physical exercise.

Folate or Vitamin B9 is responsible for converting carbohydrates into energy. Adequate folate intake is very important during periods of rapid growth, such as the ones you will experience when using Game Changer Mass. Proper Folate intake has been linked to positive health outcomes, such as a reduced homocysteine levels.

Magnesium is a “helper molecule” being used by enzymes. Magnesium helps in the transformation of food into energy, making it harder to develop stored fat. Also, Magnesium aids in the creations of proteins from other amino acids. Apart from this, it aids the nervous system, making it faster to send messages throughout the brain and nervous system, which translates into better mind-muscle connection.

Zinc is found in a multitude of cells throughout the body and has the role of enabling the immune system to fight off bacteria and viruses. Zinc improves digestion and thus allows more energy to be converted from foods. It also prevents the storage of excess fat in the body.

Chromium (as picolinate) is a type of mineral naturally found in a multitude of foods. Chromium contributes to macronutrient metabolism and maintains blood sugar at normal levels. Chromium picolinate has the highest bioavailability of all chromium sources and it can improve blood sugar levels by enhancing the body’s response to insulin. Chromium picolinate will reduce your appetite and blunt cravings, further aiding the efforts of shading the excess weight and fat.

Copper is found in all body tissues and it plays a key role in making blood cells and maintain healthy nerve cells, while also improving the immune system.

L-Carnitine’s ability to increase the human body’s energy production by consuming its fat reserves makes it a powerful fat burner. Inside the body’s cells, L-Carnitine helps transport fatty acids into the mitochondria, where they can be burned for energy. Apart from this metabolic property, L-Carnitine has been shown to improve the brain’s neurological functions and facilitate the body’s muscle coordination. Since L-carnitine helps increase mitochondrial function, it plays a key role in the body’s fight against diseases and in healthy aging. L-Carnitine L-Tartrate is a more efficient and more rapidly absorbed kind of Carnitine. It combats muscle soreness and aids in tissue recovery during and after physical exercise. Furthermore, it fortifies the body’s assault on fat reserves, while providing a boost of energy.

Alpha Lipoic Acid is a natural acid, being produced by the human body, on a daily basis. It acts as a weight loss agent, as it’s both water-soluble and fat-soluble. Furthermore, it aids in regulating blood sugar levels, and enhances nerve function and signaling. It will improve your mind-muscle connection.

CLA or Conjugated Linoleic Acid is commonly found in omega-6 fatty acids, naturally obtainable from meat and dairy products.

Green Coffee Bean Extract comes from coffee beans that haven’t been procced and roasted. The extract acts as a metabolism and blood sugar regulator. As a result, the excess sugar from the bloodstream is eliminated and more sugars and fats are going to be broke down and not absorbed by the body through a faster metabolism.

Green tea leaf extract is obtained naturally. Because it contains antioxidants and nutrients that have powerful effects on the body, it is being used to increase alertness and lower cholesterol. Through its 55% Epigallocatechin gallate concentration, Green tea leaf extract helps reduce the formation of free radicals in the body, protecting cells and molecules from damage. Green tea has been shown to increase fat burning through fat oxidation and boost the metabolic rate. Several studies showed that green tea leads to decreases in body fat, especially in the abdominal area – waist circumference and belly fat.

Tribulus Terrestris Fruit Extract has been observed to increase the levels of male specific hormone, Testosterone. With the increase of Testosterone levels, the muscles will start absorbing more protein and further enhance the accumulation of lean muscle mass. The research has shown that Tribulus Terrestris Fruit Extract can act as an anti-inflammatory agent, whilst boosting the immune system.

Panax Ginseng root extract will improve your mental focus and mind-muscle connection by increasing the energy levels. As a result, you will feel less tired, especially after intense physical exercise, while also feeling energized.  It was proved that Panax Ginseng Root Extract can lower blood sugar levels.
